Thanks for both replys. Since I don't have an existing hitch, I'm sure the cost of that plus the carrier would exceed the bike. The U bolt sounds like a possibility for slowing them down. FYI, bike theft here in Florida is big business. The gangs drive trucks, hang in mall parking lots waiting for customers to just "run into the store for a second" and have your bike and are gone in less than a minute. I was hoping someone had invented a magic device to solve the problem. I guess the only real solution, as suggested, is to plan my day to minimize leaving the bike unattended.

Thanks again.
